A constable with Lambton OPP is facing Criminal Code charges.
The force's West Region headquarters reports that 31 year-old Constable Craig Johnston is charged with obstruction of justice and breach of trust.
The charges stem from an investigation conducted by the OPP Professional Standards Bureau, and Johnston is currently suspended with pay.
Police do not say what led to the charges, which were filed on Tuesday.
Johnston -- who has been an OPP officer for 10 years -- will speak to the offences in Sarnia Court on January 7th.
